To all whom it may concern Y Be it known thatI, J OHANN AUGUST HEIN-RICH MEYER, residing at Dresden in the Kingdom of Saxony, Germany, haveinvented certain new and usef'ul Improvements in Cutters for Paper,Cloth, Ste., ot' which the following is a specification.

The accompanying drawings form a part of this specification andillustrate the invention.

Figure 1 is a front view. Fig. 2 is a crosssectiou taken on line m, Fig.1, and having the levers and link removed.

Two upright pillars or frames on a horizontal `base-plate are providedwith two guides in an oblique position, in which the knife-beam l1, withthe knife o, may be moved up and clown. Y t

The mechanism for moving thc beam h and knife o up and down consists ofalever, t', which is pivotcd at the left-hand pillar at w. `Lever t' andbeam hare connected by rod k. The free end of the lever e' is traversedby a pin or bolt, q, forming the pivot for leverf. -The boss ot' thislever is partly furnished atv its periphery with teeth taking into theteeth which' are formed at the upper end of the pillar or frame r. Theseteeth on pillar or frame r constitute a txed or standard wreath otlteeth otl an elliptical form. As the teeth on the boss of` the lever fare arranged eccentrically to the center of motion g, as shown in thedrawings, it follows that it' this lever f is turned from the positionshown (at the left side) into the opposite position (to the right side)the motion of part 1I 7c h will, in' consequence of the proportions ot'parts or of transmission, be a rapid one in the beginning, decreasingtoward the end ot the motion ot' the lever f, whereby the cutting of theknife o througha layer oflcloth, paper, 6to., put underneath thepress-beam e will be accomplished` with ease. "'lhe presser-beam e hasattached to its lower edge, at either end, the arms d, which extend downthrough openings inthe table and are pivoted t0 the rod e. The lever dc, pivoted at one end to the bar c and fulcrumed at a proper Y pointinits length toa stud projecting beneath the table, is attached to thelower end of a screw-rod, c, with the top of which, above the table, ahand-wheel, b, engages. This handwheel is collared to the platform asshown. By turning the hand-wheel b in one direction or the other the endc of the lever d c vill be raised or depressed and the end cl eontrarilyaffected, so that the frame d d c andthe attached presser-beam e areaccordingly raised or lowered and made to bear with any required degreeof force upon any thickness of material. The knife o, after cutting thelayer ot" cloth, paper, Sac., underneath the press-heath, enters into astrip of wood or other suitable material, which is placed in a slot orgroove ot' theplate n, This plate is arranged to be moved horizontally,so that the strip ot' wood or other material may be moved with the platen. rlhis movement ofthe plate is effected by the handcrank m of thescrew m, which screw passes through a bracket, n', which projectsunderneath from the plate u, and which bracket is provided with internalthread corresponding to screw m. This shifting otl plate u with itsappendix has for its object tootfer to theknite o as often as necessarya new part ofthe face .of the strip of wood, for thc purpose of cuttingall parts of the layer eqn-ally smooth.

In order to determine thelength of samples to be cut, the apparatus isprovided, as in ordinary paper-cutting machines, with an angle, j),which may be shifted according toa scale provided for this purpose.`

I claiml. In `a sample-cutter, the combination of a knife moved up anddown in oblique ways of a presser-beam, E, mounted upon the moving framed d e', the i'ulcrumedlever d c, screw a.,

and hand-wheel b, for operating said presserbeam, substantially as setforth.

2. In a snnplecntter, the fixed eccentric r, in combination with themovable eccentricgear ou the hand-lever fand with the lever i and linkk, connected to the cutter li o, all arranged for joint operation, asherein specified.

ln testimony whereofl havehereunto set my hand in the pre-sence of twosubscribing witlleSSS.

JOHANN AUGUST HEINRICH MEYER.
